Fungal infections on your hands, feet, or nails are no fun. Our guide will show you how to treat some of the more common fungal ailments, and we also have tips about when you should see your doctor.

Method 1

Method 1 of 3:

Using Topical Antifungal Treatments

1
Purchase over-the-counter anti-fungal cream and ointments. If you have an infection of the skin or nails that affects only a small area and does not cause much irritation, you may consider trying over-the-counter treatments before seeing your doctor.^{[1]

Wash your hands before and after using the treatment. Make sure your hands are as clean as possible before touching the affected area. Run warm water over hands and clean them with antibacterial soap. This can help prevent you from irritating your skin even further. Washing your hands after you touch the affected area can help prevent the infection from spreading elsewhere.

Follow the instructions on the treatment's label. Most topical antifungal treatments need to be applied directly to the infected area. Refer to the instructions on the label of your treatment to ensure that you use it correctly. In most cases, place a small amount of cream or ointment on your fingers and rub it directly onto the infected area.^{[3]

- Do not use topical treatments more than the product’s label directs you to, unless your doctor has told you otherwise.
4
Let the cream or ointment dry before putting on socks or shoes. You want to make sure the treatment absorbs into your skin or nail rather than any fabric around your foot. Avoid taking a bath or shower immediately after applying the treatment.
5
Stop using the treatment if you have adverse side effects. If the cream or ointment you’re using gives you a rash or seems to make your condition worse, stop using it immediately. Contact your doctor if the side effects don’t go away in a few days.
6
See your doctor if over-the-counter remedies don’t help. If your symptoms don’t improve within 2 weeks, seek medical attention. Seek medical attention immediately if your infection spreads or starts to cause greater irritation. In most cases, your doctor will prescribe stronger antifungal medication. Use this prescription medication only as directed.^{[4]

Method 2 of 3:

Taking Antifungal Medication

1
See your doctor if you think you might have a fungal infection. Fungal infections of the skin can produce rashes, irritation, or discoloration. Fungal infections of the nails often make nails look yellow and brittle. Other types of fungal infections can seem like more common illnesses, such as bronchitis or the flu. Seek medical attention for any persistent symptoms, especially if you have a weakened immune system.^{[5]

Pick up your prescription from your local pharmacy. In most cases, your healthcare provider will prescribe antifungal medication that you can take at home, like fluconazole. Fill this prescription at a drugstore or pharmacy of your choosing.^{[6]

Follow your doctor’s orders carefully. Your doctor will most likely give you instructions when they prescribe medication to you.

Contact your doctor if you have severe side effects. Severe side effects of antifungal medication can include nausea, vomiting, unusual bruising or bleeding, and loss of energy.

Schedule follow-up appointments with your doctor as required. In many cases, you will need to take antifungal drugs for several weeks or months. Your doctor may ask you to come back to their office so they can check in to see how the treatment is progressing. You may also be asked to take a blood test so your doctor can ensure that the drugs are not harming your liver.^{[12]

Soak the affected area in a vinegar mixture once a day. Mix 1 part vinegar with 2 parts water in a clean bowl or foot basin. Soak the affected area for 10-15 minutes once a day. It may take 2-3 weeks to see improvement in your condition. Vinegar soaks work particularly well for athlete’s foot and mild cases of nail infections.^{[17]

Apply snakeroot leaf extract to the affected area. Purchase this extract online, as not all drugstores carry it. Apply it by using the dropper to put the liquid directly on the skin. Then, rub the liquid into your skin. Use the extract for 3 months to get the best results. Apply it 3 times a week the first month, 2 times a week the second month, and just 1 time a week the last month.^{[18]
